(Embodiment 1)
The workpiece attachment structure of this embodiment is a structure in which the workpiece 50 is attached to the front surface of the board 40 via the board anchor 1 and the dedicated locking tool 2. 1 and 2 show the attachment process, and FIGS. 3 to 6 show each member used in the attachment structure. In the text, the side where the workpiece 50 is located with respect to the board 40 is referred to as “front”.

  The board anchor 1 has the same configuration as the board anchor 100 shown in FIGS. That is, the board anchor 1 is mainly composed of a cylindrical socket 3 and a screw member 10 inserted into the socket 3 as shown in FIG. The socket 3 has a structure in which the first cylindrical portion 4 and the nut-shaped second cylindrical portion 5 are connected by a plurality of split pieces 6. The screw member 10 has a structure in which a head 11 having a larger diameter is formed at one end of a male screw rod 12.

  The first cylindrical portion 4 has a structure in which a flange 8 is extended outward from the front end edge of the cylindrical body 7 penetrating both ends. From the flange 8, a plurality of sharpened locking pieces 9 are protruded rearward. A female screw (not shown) is formed on the inner peripheral surface of the nut-shaped second cylindrical portion 5, and this female screw is provided in a size and shape that meshes with the male screw rod 12 of the screw member 10.

  The locking device 2 includes a rectangular plate-shaped flange facing plate 15 having a diameter larger than that of the flange 8 of the first cylindrical portion 4, and screw enclosures extending forward from the four sides of the flange facing plate 15. This is a generally hat-shaped metal fitting comprising a plate 16 and a locking plate 17 extending outward from the front end portion of each screw surrounding plate 16 (see FIG. 5 and the like). An insertion hole 18 through which the male screw rod 12 of the screw member 10 is inserted is formed through the center of the flange facing plate 15. The insertion hole 18 has a larger diameter than the male screw rod 12 and a smaller diameter than the head 11 of the screw member 10.

  As shown in FIG. 1, according to the work attachment structure of the present embodiment, the work 50 can be reliably attached to the front surface of the board 40 without pulling out the screw member 10 once. Specifically, it is as follows.

  First, a board-side attachment hole 41 is formed through the attachment portion of the board 40, and a workpiece-side attachment hole 51 is formed through the center of the workpiece 50 (see FIG. 2). The opening of the board side mounting hole 41 is smaller in diameter than the flange 8 of the first cylindrical portion 4 and larger in diameter than the cylindrical body 7.

  The work side mounting hole 51 has a two-stage structure in which a front side portion is opened larger than a rear side portion. Specifically, the workpiece-side mounting hole 51 has a structure in which a rear-side mounting hole 52 and a front-side mounting hole 53 having a larger diameter are communicated in a straight line in the front-rear direction via a ring-shaped stepped portion 54 when viewed from the front. It is. The rear mounting hole 52 has a larger diameter than the flange 8 of the first cylindrical portion 4 and the flange facing plate 15 of the locking tool 2, and a smaller diameter than the outer peripheral edge of the entire locking plate 17 of the locking tool 2. It is. The front attachment hole 53 has a larger diameter than the outer peripheral edge of the entire locking plate 17.

  Then, as in step (i) in FIG. 1, the work 50 is set on the front surface of the board 40 so that the board-side mounting hole 41 and the work-side mounting hole 51 are coaxially positioned (FIG. 2 (a). )reference). Next, as in step (ii) in FIG. 1, the board anchor 1 is inserted into the workpiece side mounting hole 51 from the front side of the workpiece 50.

  Here, the board anchor 1 is preliminarily combined with the above-described dedicated locking tool 2. The locking tool 2 is interposed between the screw member 10 and the socket 3 (see FIGS. 3 and 4). That is, the rear surface of the flange facing plate 15 of the locking tool 2 and the flange 8 of the first cylindrical portion 4 of the socket 3 are arranged to face each other, the insertion hole 18 of the flange facing plate 15 and the internal penetration of the first cylindrical portion 4.

  Here, when the screw member 10 is tightened, the nut-shaped second cylindrical portion 5 that meshes with the screw member 10 moves forward and approaches the flange 8 side (see FIGS. 4A and 4B). Due to the approach of the second cylindrical portion 5, an external force sandwiched forward and backward acts on each of the plurality of split pieces 6, and the board 40 is sandwiched between each bent split piece 6 and the flange 8 (FIG. 2 (c). )reference).

  The workpiece 50 is attached and fixed to the front surface of the board 40 by the steps (i) to (iii). As shown in FIG. 2 (c), in the work side mounting hole 51 (rear side mounting hole 52) in this mounting state, between the head portion 11 of the screw member 10 and the flange 8 of the first cylindrical portion 4, The flange facing plate 15 of the locking tool 2 is sandwiched. Further, the locking plate 17 provided in the locking tool 2 is locked to the stepped portion 54 of the work side mounting hole 51.

It is smaller in diameter than the outer peripheral edge of the second locking plate 17.

  Therefore, as shown in FIG. 7A, the board side mounting hole 41 and the work side mounting hole 51 are set so as to be positioned on the same axis, and the locking tool 2 is combined in the work side mounting hole 51. When the board anchor 1 is inserted, as shown in FIG. 7B, the locking tool 2 is fitted into the work side mounting hole 51. Specifically, the flange facing plate 15 and the screw surrounding plate 16 of the locking tool 2 are positioned in the workpiece-side mounting hole 51 without a step, and the locking plate 17 of the locking tool 2 is positioned at a position where it contacts the front surface of the work 50. To position.

  When the screw member 10 is tightened, the plurality of split pieces 6 are bent so as to bulge outward by the advancement of the second cylindrical portion 5, and the bent split pieces 6 and flanges are bent as shown in FIG. The board 40 is sandwiched between the two. At this time, the locking plate 17 extending in a flange shape from the front end edge of the locking tool 2 is locked to the peripheral portion of the workpiece side mounting hole 51 on the front surface of the workpiece 50.

  The elastic member 20 has a central hole 21 having a size slightly larger than the outer peripheral edge of the entire screw surrounding plate 16 of the locking tool 2 at the center. The dimensional shape of the outer peripheral edge of the elastic member 20 is provided so as to match or substantially match the dimensional shape of the outer peripheral edge of the entire locking plate 17 of the locking tool 2. Accordingly, the screw surrounding plate 16 is passed through the central hole 21 of the elastic member 20, and the elastic member 20 is disposed so as to contact the rear surface of the locking plate 17 of the locking tool 2. The work 50 may be attached and fixed in the same procedure as in the case.

  The elastic member 20 after mounting and fixing is sandwiched between the locking plate 17 and the board 40. That is, the locking plate 17 is locked to the peripheral edge portion (that is, the stepped portion 54) of the work side mounting hole 51 through the elastic member 20.

  By the way, in the workpiece mounting structure using the locking tool 2, if there is a variation in the size and shape of the locking tool 2 or the dimension of the work-side mounting hole 51, the locking tool 2 is stably locked to the work 50. It becomes difficult to do. On the other hand, if the elastic member 20 like this embodiment is used, these dimensional variations can be absorbed by the elastic member 20.

  Needless to say, this elastic member 20 can also be employed in the work mounting structure of the second embodiment.
